Scientists discover new genetic clues to breast cancer

UK scientists have identified five more genetic sites that increase a woman's risk of developing breast cancer.

The discovery, which is detailed in the journal Nature Genetics, brings the total number of common 'low-risk' genetic sites that are linked with the disease to 18.

According to the researchers, the five new genetic variations increase an individual's risk of developing breast cancer by between six and 16 per cent.

In the long term, it is hoped that a test can be developed that looks for a combination of these genetic variants in order to aid prevention and treatment decisions for those who are most at risk.

Study author Professor Nazneen Rahman, from the Institute of Cancer Research, said that although 18 gene regions have now been identified, 'we still don't know which genes are causing this increased risk'.

'Identifying the underlying genes and mechanisms behind breast cancer development is essential to increasing our understanding of the disease and ultimately finding new treatments,' the researcher added.

Dr Helen George, head of science information at Cancer Research UK, which helped to fund the study, added: 'This research takes us a step closer to developing a powerful genetic test for the disease.'

Genetic tests are already available for certain gene faults that are known to increase a woman's risk of developing breast cancer, including BRCA1 and BRCA2.
